Cyclodextrins and their applications in analytical chemistry
Article Abstract:
The ability of cyclodextrins (CD) to form inclusion complexes with a wide range of guest molecules, from neutral and ionic organic/inorganic compounds to noble gases, allows their use in chemical analysis. In spectrometry, CDs impart solubility to analytes and dramatically enhance signals. In electrochemical analysis, CDs are highly selective towards certain isomers and anionic guests. But it is in chromatography where CDs shine, serving as chiral stationary or mobile phase or both, as enzyme inhibitors in affinity techniques and as chiral recognition agents in electrophoresis.

Industrial applications of cyclodextrins
Article Abstract:
The formation of complexes with cyclodextrins for industrial use often involves water to induce the hydrophobic interaction between the guest and the cyclodextrin cavity. The conventional techniques for complex formation are the coprecipitation technique, the slurry process, the paste technique and the dry mixing process. The uses of cyclodextrins include control of solubility, process aids, stabilization, masking of the effects of the guest, reduction of volatility, directing of chemical reactions and regulation of fluorescence and light absorption.

Photofunctions of intercalation compounds
Article Abstract:
The surface properties and the host-guest interactions of the intercalation compounds are studied from spectroscopic properties. The host-guest interactions are important to ascertain the guest species' adsorption states. The orientations of the guest species are largely affected by their size and the host layers' charge density. Coadsorbates can also change photoactive species' aggregation, and electron-energy transfers may happen.
